I purchased Samsung f41 phone on April 2021 and in May 2022 i updated the software that samsung was sending continues notification after updating software my phone started hanging and autorestart, took to service centre and they informed that it is mother board issue and it needs to be replaced and that costs 7000 almost half of the phone's cost.
